My invention relates to railway rolling stock and consists in anewlocomotive framing structure.l

The main object of my invention is to combine the locomotive bed or mainframe and associated parts with a reservoir for'I terminating in th@compressedv air'in such manner as to form a stronger vframe and toeliminate the necessity for the usual Separately formed reservoirs atthe sides of the boiler or superstructure.

. lBy means of my the air reservoir in the main frame at little l. or noadditional cost of the latter and I v eliminate the expense of the steelreservoirs heretofore used yand eliminate the maintenance of the latter,landl provide additional A space at the side of the boiler shell forother ventioii,

. equalizer fulcruiiis, brake brackets, cradle, deck plates,

spring hanger bearings, expansion plate ilot beam and steam cylinders.ld

It will be understood vhat the inclusionI `of all these elementsis.unnecessary to l the use of the essential features of my invention.v

' In the accompanying drawings which illustrate my 1invention-- A takenapproximately on a modi Figure 1 isal one half longitudinal top view ofthe locomotive-'bed. y

Figure 2 is a` side elevation of ythe. same with superstructure.

Figure 3 is a verticalv the line 3 -3 of ligurel.l Figure 4 is 'asimilar, section illustrating 'lied form of my invention. i l AIn all ofthese figures the wheels are indicated in dot and dash\l`ines. The frameincludes spaced 1, preferably4 of box cross section, having pedestaljaws 2, equalizer fulcrums 3, and brake hanger brackets 4formed.'integral ly therewith. The rear endsof side members 1 areextended to form the cradle sides 5 -which ,arev connected at their rearends' by invention, Il can embody hangen` and boiler saddle,

fand to provide for the escape of gases during the casting operation, Iprovide suitable "openings in the top and bottom walls ofthe transversesection side members f deck plate 6 having extensions 7 for mounting theside bearings (not shown) which 'will rest upon the trailer truckframc'(iiot shown). The forward ends f-side members 1Inerge with eachotherandare extended forwardly toV forma front deck 8 pilot beam 9. Theboiler saddle is indicated at 1-0 and is preferably formed integral withthe side members and deck and cylinders 11. Between side membersbackbone of the bed and transmits bufn'g and pulling .forces and alsoreinforces the 'ranie transverselyaid vertically. By niaking member 12hollow and closing its ends,

I adapt the same to be used as an air reser voir taking 'the vplace ofthe usual tanks made of sheet steel Aand mounted at the side' oftheboiler shell. The boiler is shown at A andthe air compressor at B, thepipe connections between air pump and reserv'oir being indicate/d at C.

In my preferred construction, I illustrateinember 12 as being ofcylindrical shape and inv order. to support thycores' in the moldreservoir. After the fcasting is completed, and the core lsand removed,these openings 1, I provide a' main, longitudinal mei'nbe'r 12 whichforms the can be closed by means of the plates 13.

The openings are elongated so that eachv plate can be(insertedlengthwise and then turned lto the position shown. The plates may `bewelded in position, as indicated at W, or they maybe ysealed in place bybolting or other-clampingmeans.

. Members 1 and 12 are connected by verticallyspaced webs 14 which unitewith the adjacent walls of members 1 and 12 to form ya substantiallycontinuous box shaped member on each side of member 12, thusfurtherreinforcing the frame and providing astruc ture which is rigidl andadapted to resist deflection in everydirection. Webs 14 may beperforated at intervals, as indicated at 15, to provide for applicationofl driver spring saddles l27 on top of driving boxes construction.

and to lighten the casting and *improve castlspace between member 12 andthe boiler 17,

brackets `18 may extend clear across the fra-me further reinforcing ittransversely. Where this space will not permit a continuous bracket, orsame is not desiredfor other' reasons, the bracket may` be divided asshown (Figure 3), f In Figure 4 I illustrate a modified construction inwhich the side members 21 and the parts associatedtherewith are substantially the same as in the preferred construction, but the centralbackbone air reservoir forming member 22 is illustrated as being ofrectangular or box shaped cross'section and the longitudinal brace 23whichpreferably will extend the fulLlength of member 22 is disposedvertically rather than horizontally, as does brace 16 in the' preferredA series of openings 3() are provided in brace 23 for molding purposesand for lightening the casting. lThe openings in member 22 are closed bymeans of plates 29 `lwelded to the casting at W.

The connection between the central memhorizontal webs 26,11. which, withthe adjacent walls of members 21 and 22, form a box` shaped connectionbetween the center and side of the underframe. i
